7 Claims. (01. 30-51) The present invention relates to safety razorsclamp and guard member 12 is provided with and has for its objects theprovision of a simple, trunnions ll engaged in notches I8 in the endinexpensive device in which a wafer blade may walls whereby the memberI2 is tiltably and be readily inserted and as readily removed; removablyengaged in the housing II. This which may be easily cleaned; which,while T- member at its forward end is provided, in the 5 shaped when inuse, may be arranged with the usual manner, with a guard portion l9 anda head and handle in parallel relation for occublade clamping portion20.

The handle is Fig. 6 is a similar view showing the mannerthen swung to the position shown in Figures 1 of disengaging the handlefrom the head. and 2, the cam lug 28 engaging the under face Fig. 7 is aplan view of a preferred form of of the plate l2 at its off-set to rockthe plate 45 blade. about its trunnions so the portion 20 thereof Fig. 8is a partial vertical sectional view of clamps the blade against theunder face of the an alternate form of razor head. housing top I4. Theblade is now effectively In the present form of the invention the razorpositioned in the razor against displacement. comprises a head portion10 consisting of a In the above manner, the parts may be again 50housing H, a clamp and guard member I 2, and manipulated for the removalor replacement of a handle [3 normally arranged at right angles a blade.to the head. It will be noted that the cams 21 and 28 at The housing It!is preferably formed with a all times control the movement of the platetop [4, and walls l5, and a rear wall E6. The I2, the cam 21 serving toopen the head and 55 retain it open, and the cam 28 serving to close thehead and retain it closed.

The detent 30 insures proper positioning of the handle during shavingand the off-set 22 in the plate l2 permits the application ofconsiderable clamping pressure by the cam lug 28 since said plate mayflex slightly under the force of this pressure.

The razor structure, as above described, permits of movement of thehandle in either direction. At times it is desirable, however, to storethe razor in a small space. For this purpose, therefore, one of the camportions 3| may be omitted as shown in Figure 5 so the handle l3 may beswung in the direction of the arrow 34 without moving the clamping platel2. In this condition, a razor containing a blade may be carried, as forinstance, in a convenient coat pocket. When it is desired to remove the.blade, the handle is swung in the direction of the arrow 35 and theaction is as above described.

Ordinarily, it is sufiicient to shake the razor after washing to free itof excess moisture before storing. However, at times it is necessary tothoroughly clean all the razor parts. This is best accomplished when allthe parts comprising the razor are disassembled. In the present instancedisassembly of the parts may readily be done by providing the pivot pin25 with flattened portions 35 which adapts said pin. for movement alongthe open slot ii'l in the member 24. When the handle I3 is thus removed,the plate 52 may be removed from association with the housing H.

In the form of the invention shown in Figure 8, the head is formed as anintegral member comprising the top wall H and the clamp and guardportion li resiliently associated so that normally these portions arespaced (dotted lines) for the reception of a blade when the handle l3 ispositioned parallel to the head, and are in clamped relation as shownwhen the handle is in right angled position. This structure provides arazor of extreme simplicity and durability which is quite economical tomanufacture.

While the above is descriptive of the preferred embodiments of the razoras illustrated, it is apparent that immaterial changes in design may bemade by skilled persons without departing from the scope of theinvention as hereinafter claimed.

What I claim as new and desire to secure by Letters Patent, is:

1. A razor comprising a head portion consisting of pivotally engagedmembers, and a handle for the razor, pivotally connected to one of saidmembers, said razor handle being provided with cam means for positivelyrocking the other of said members toward and away from blade clampingrelation when the handle is rocked.

"2. A razor comprising a head consisting of a housing and a bladeclamping member pivotally associated therewith, a handle for the razor,pivotally connected to the housing, and cam means on the razor handlefor positively rocking the clamping member into and out of bladeclamping relation with the housing when the handle is rocked.

3. A razor comprising a head consisting of a housing and a bladeclamping member pivotally associated therewith, a handle pivotaliyconnected to the housing, cam means on the handle for engaging a rearportion of the clamping plate when the handle is swung in one direction,and cam means in the handle for engaging a front portion of the clampingplate when the handle is swung in the other direction.

4. In a razor, a housing, a guard and blade clamping member pivotallyconnected with said housing, an extension on said housing, said guardand blade clamping member being formed with an opening for theprotrusion of said extension, a handle pivoted to said extension, andcam means on said handle for rocking the guard and blade clamping memberwhen the handle is rocked on its pivot.

5. In a razor, a housing, a guard and blade clamping member pivotallyconnected with said housing, an extension on said housing, said guardand blade clamping member being formed with an opening for theprotrusion of said extension, a handle pivoted to said extension, cammeans on the handle for moving the guard and blade clamping member intoblade clamping relation with the housing, and cam means on the handlefor moving said member into blade releasing relation with the housing.

6. In a razor, a blade clamping head, comprising a housing and a bladeclamping member pivotally associated with the housing, a handle arrangedsubstantially at right angles to said head when a blade is clampedbetween the housing and the clamping member, and means on the handle forpositively moving the clamping member and thereby freeing the blade whensaid handle is moved from the mentioned right angle position.

7. In a razor, a housing having a top, rear and side walls, a memberpivotally connected to said housing and having a front blade clampingportion and a rear portion, a downwardly reaching extension on saidhousing, a handle pivoted to said extension, cam means on said handleengaged with the front blade clamping portion of the mentioned member,and cam means on said handle engaged with the rear portion of saidmember, whereby upon movement of the handle about its pivot, thementioned member is moved.
